Of course the math check out, they are correct, but in my opinion, time is not a dimension, it's the 'refresh rate' of matter.

To me, there are only 3 dimensions, that of space.

That does not mean the relativity math is useless. On the contrary, what they describe is real and we can experimentally verify it.

But that does not mean we can 'move' into time, as we 'move' into space. That's why time is not a dimension.

Exactly. Time is just a very useful fudge to describe change. If nothing changes, there's been no time. If something changes, there has been time.

A dimension is just a useful number that you can operate on. You can have a physics where the fourth dimension is how blue something is, and the fifth dimension is how good Mary thinks it tastes.

How does your refresh rate time accounts for time slowing down for things moving fast (relative to you) regardless of spatial direction they are moving?

Spacetime simplifies many things for example in that framing nothing is ever at rest or nothing ever travels at different speed. The speed of everything is the same, it's just that things spatially at rest have all their speed in the direction of time. Accelerating something in spatial direction is rotating (mathematically) their motion away from time direction, into some spatial direction. This requires energy so the time direction is lowest energy but to rotate it away from it you need to put in energy. If you want to rotate it to 45 deg you need infinite energy.

The refresh rate doesn't slow down, but the speed at which things change does, at high speeds.

I don't believe refresh rate captures the transmission of time onto other objects it would only capture individual time, they have to sync up somehow and gravity affects it so its not just matter, its the impression of matter onto the fabric of space

[lottin]

Space has no 'fabric'. Space is not a physical entity, but a set of coordinates.

"refresh rate" implies discrete steps, whereas not only we haven't discovered such (planck time is not it), but also we have no idea how a transition between different refresh rate would look like...

To me, dimensions are just more columns in a table. Seeing in 10 dimensions? No prob.
